Product description
Contains diameters 4, 5, 6, 8 a 10 mm; Step-Tip makes precise drilling easier without pre-drilling.
★Key features
- HSS-G ground drill bits DIN 338
- DIN 338, type N, right-hand cutting
- practical packaging according to the specific set
- Step-Tip point for drilling without pre-drilling
- split point
➤Application
- metal drilling
- workshop, installation and service use
- use in materials: alloy steel, non-alloy steel, iron, cast iron and non-ferrous metals
⚙Technical parameters
- Thanks to the Step-Tip point, the drill does not wander when starting and pre-drilling with smaller diameters is not required. The drill reaches the required diameter in one step without changing tools. The TiN coating increases resistance and extends point life.
- Design:
- DIN 338, Type N, right-hand cutting
- higher quality metal drill bits
- special Step-Tip point - more precise starting, the drill does not wander and cuts into the material better
- thanks to the stepped point, pre-drilling with smaller diameters is not required - the drill reaches the required diameter in one step without changing tools
- point with TiN coating - higher resistance and longer point life
- from diameter 3.0 mm, the point has a split point - the drill cuts into the material better and does not require centre punching
- from diameter 4.0 mm, shank with 3 flats (against slipping in the chuck)
- silver finish (gold TiN point)
- Use in materials: alloy steel, non-alloy steel, iron, cast iron, non-ferrous metals
- Included sizes: 4 | 5 | 6 | 8 | 10 mm
- Individual pieces can be purchased separately if needed (item no. 3620ST)
- Packaging type: robust plastic case
＋Additional application information
- When working, choose suitable speed, feed pressure and cooling according to the material and tool type.
- Further practical information on selecting and working with tools can be found in the category description Metal drill bit sets.
